摘要
线缆耦合是HEMP对电子系统作用的主要途径之一。传输线模型是分析场线耦合常用的研究方法。针对影响线缆中电压、电流响应的几个关键因素,如地面附近的电磁环境、所采用的传输线分析模型、地面土壤电导率以及线缆架高等,计算了线缆的响应,并从机理上给出了解释。所得到的分析结论对于实验研究及防护设计都有参考意义。
Aerial lines or cables, as one mainly energy transport path of electronic system when illuminated by HEMP, has been often modeled by field-to-transmission line model. However, in many cases, we too often encounter some confusing statements to the lines effects during experimental procedure. The aim of this paper is to present and discuss these cases, such as the electromagnetic environment above the ground plane, the contribution of the different electromagnetic field component to the induced current and voltage, variations of the load current for different line heights and ground conductivities etc.
